Rated 5 out of 5 by from My head isn't broken. It works. Bought this for a caving trip in southern Indiana. It obviously worked because my head isn't cracked open. It fits well, its comfortable. The roof of the cave didn't really scratch it up. The straps cleaned up easily. The clips on the side held my headlamp in place without issue. It is not itchy. The vents are helpful for retaining or bleeding heat as needed. The petzl elios is an affordable and good caving helmet. It works as described and designed.

Rated 4 out of 5 by from Great helmet Some pros: it's light, it has adjustable vents, adjustments are easy to use, clips for headlight. Some cons: seems to sit a little high on my head, and look a little awkward. Overall I really like this helmet, had all the features that I wanted for spelunking/climbing/repelling. It will definitely be my go to helmet.

Rated 4 out of 5 by from Great helmet for great price I tried on some more expensive climbing helmets that i thought would look a lot cooler like the Black Diamond Vapor Climbing Helmet. However they all looked so bulbous on my head and weird. So i ended up just going with this guy. Pretty happy with it does what it needs to do and is pretty rugged compared to the lighter helmets. I would definitely go in and try them on before buying to see if you like the way they look and to make sure you get the right size

Rated 5 out of 5 by from Easily adjustable. At first I ordered size 1, and even though I was within the size range for that one, it seemed to sit on top of my head instead of covering my head. At the store, they let me exchange it for size 2, which fits perfectly. It has proper head coverage, and the straps on it are easily adjustable.

Rated 4 out of 5 by from Great helmet for the price I got this helmet for caving/climbing. I have used this model before as a loaner and liked it. The straps are a bit short for people with a large head like myself but it fits well, and is comfortable. The vent are nice to control your heat when you are underground. I would recommend it to another beginner like myself.

Rated 5 out of 5 by from Light and Solid I bought this helmet two weeks ago for an outdoor climbing, and this helmet is also my first one. It's very light and the ventilation is good in sunny days, so sweating won't be a problem. The price is well under my budget.

Rated 4 out of 5 by from Comfy, entry level brain bucket I like the hard shell. The suspension system is comfy-ish. The headlamp retainers work, but are a little hard to work with if you have a thick strap on your lamp.

Rated 2 out of 5 by from Chin strap is very short and hard to unsnap. Guys, this was a size 2, which supposedly is the bigger size. We did eight hours of caving the other day, and the straps chafed my ear the whole time, also it's hard to unsnap the buckle, I actually have to try to slide the whole helmet off (which is tight as heck due to the short straps) and then unsnap it. It's relatively a nightmare. You have been warned. Straps were at maximum length.
